Hi,

We've only validated on Ubuntu 14.04 and 16.04. We use the standard Linux terminal instead of the terminal inside CCS.

Which terminal application are using using (linux's or CCS)?
Which version of Ubuntu are you using?
Which version of CCS are you using (please be more specific than CCS8)?
Which SimpleLink SDK are you using?

Can you run one of the examples supplied by the SimpleLink SDK that sends data out the UART and use scope/logic analyzer to confirm the target is sending the data out correctly?

Todd

Thanks for your reply!

Here are some of the points you mentioned:

Which terminal application are using using (linux's or CCS)?

an:

user@user-N551JM:~$ help
GNU bash, version 4.3.48(1)-release (x86_64-pc-linux-gnu)

Which version of Ubuntu are you using?

an:

user@user-N551JM:~$ uname -a
Linux user-N551JM 4.15.0-47-generic #50~16.04.1-Ubuntu SMP Fri Mar 15 16:06:21 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

Which version of CCS are you using (please be more specific than CCS8)?

an:

Code Composer Studio

Which SimpleLink SDK are you using?

an: Release Name: simplelink_cc2640r2_sdk_02_30_00_28

Can you run one of the examples supplied by the SimpleLink SDK that sends data out the UART and use scope/logic analyzer to confirm the target is sending the data out correctly?

an: You mean to directly connect the UART (TX,RX,GND)of CC2640R2F to pc with a rs232 level conversion? Is there a direct ccs project for testing uart port in CC2640R2_LAUNCHXL ?

Thanks a lot!

update:

1. Which terminal application are using using (linux's or CCS)?

Welcome to minicom 2.7
OPTIONS: I18n
Compiled on Nov 15 2018, 20:18:47.
Port /dev/ttyACM0, 11:33:15

2. Which SimpleLink SDK are you using?
I tried SDK version simplelink_cc2640r2_sdk_2_40_00_32， and that's the same problem.

Thanks!

Hi,

We have <sdk>/examples/rtos/<board>/drivers/uartecho. The target simplies echos back the character that the terminal sends it. Complete details (baudrate, etc.) are in the readme in the project. Try this and see if you get Rx and Tx. Note: it uses the back-channel UART in the USB/XDS110 connection.
